A.) 2a+6b
Explanation:
multiply each term in parentheses by 2
2a+2x+3b
calculate the product
2a+6b
4 tens = 40 and 5 tens = 50 … therefore the number has to be between 40 and 50
So: 40 < x <50 … this says that x is greater than 40 and less than 50
So the possible numbers would be: 41,42,43,44,45,46,47,48,49
Now the number must have 9 ones … which mean the only number would be 49
The height of the telephone pole = 9 / 1.5 = 6 meters
(x1,y1) = (-37,47)
(x2,y2) = (26,32)
Now, m = (47-32) / (26+37)
m = 15 / 63
m = 5/21
So, the slope would be 5/21
Hope this helps!
